Yersiniosis is a kind of infection caused by the bacterium Yersinia enterocolitica. Most individuals develop this virus after consuming undercooked or raw pork. Other creatures that may provide it include horses, rabbits, sheep, cows, and rats. Cats and dogs may also transfer the bacterium, but less often. Younger kids are particularly prone to yersiniosis.

Furthermore, this infection produces fever as well as gastrointestinal issues like diarrhea. Numerous cases of yersiniosis recuperate on their own. However, medications might be required to kill the bacterium. Other health problems, including joint discomfort and rash, may occur in rare cases due to yersiniosis.


The signs of yersiniosis differ based on the age of the afflicted individual.

Typical symptoms in younger kids include:

  • Diarrhea (sometimes accompanied by blood)
  • Abdominal pain
  • Fever

In older kids and adults, signs of yersiniosis could include:

  • Right abdominal discomfort, which might be mistaken for fever 
  • Fever

Symptoms usually appear 4 to 7 days following exposure and can persist for up to 3 weeks. Germs migrating to the bloodstream, joint discomfort, and skin rash are all potential dangers.


Your doctor will interview you regarding your problems and do a physical exam. They might ask for a fecal sample and submit it to a laboratory since yersiniosis is usually confirmed by finding the germs in an affected person’s feces. Because numerous labs don’t regularly test for Yersinia, clinicians must notify labs whenever yersiniosis is detected so that specific tests may be performed. 

Furthermore, it will also be able to identify through:

  • Blood
  • Bile
  • Urine
  • Joint fluid
  • Lymph nodes
  • Saliva samples in the throat


Yersiniosis usually improves without the need for medical therapy. Your body eliminates the bacterium that makes you unwell. However, it might require many weeks for signs to disappear entirely. Consume lots of fluids while healing to lower your chances of dehydration. When your yersiniosis is severe, you might require prescription medications to kill the germs. Antibiotics can also be employed to cure more severe or complex illnesses.

There are certain precautions you may take to avoid. This includes refraining from eating undercooked or raw pork and using only pasteurized milk products. In addition, always clean your hands with antimicrobial water and soap before eating or cooking food, touching pets, or managing raw meat.
